Michael Crichton

Guy who wrote Jurassic Park and many more. Also helped to create E.R.

Westworld (1973) -- Michael Crichton's first time as a feature film director, this is sort of an early version of Jurassic Park, with robots gone crazy in an amusement park for adults. Although the idea is underplayed, it seems that the "malfunction" of free will is transmitted sexually. Kind of fun to watch in a goofy sort of way. (Richard T. Heffron directs the sequel, Futureworld.)
